Research Areas:• Database Anomaly Detection: Developed and researched database anomaly detection algorithms in Python. Wrote modular and well-tested codes to integrate models and algorithms to a product prototype. • Query Classification: Worked using LSTM Autoencoder on Keras and Tensorflow on parsed queries to learn embeddings for query classification. Published a paper on role-based access control query classification using machine learning models such as CNN, Random Forest, SVM, Naive Bayes.• Federated Machine Learning: Developed and tested secure regression models for private and secure machine learning in Python. Analyzed and researched on machine learning attacks in secure multiparty computation and partitioned data.
